We're only one or two signings away from literally having two great teams, first the team that has brought recent succes:
Then with two or three signing we could field a completely different 11. Except for Rooney, because the captain always plays.
Obviously we are looking at reinforcing our midfield first, since Van Gaal made comments about that. It makes sense too because it's odds on us being fecked if something happens to Carrick, though we could still win games with Blind, Ander or Fella playing his position, but it's not ideal. My guess: someone like Vidal or Schneiderlin. But who knows?
Last summer Van Gaal also said it was quite obvious we want to strengthen our defense. Hummels is a player who'd bring something different and he's better than Evans. But having Smalling, Jones and Rojo is already great, their injuries are the main concern. Rafael could be replaced with Clyne if he's unhappy or Van Gaal doesn't trust him. But given the fact that Van Gaal used Young and Rafael at LB too this season, I can see him wanting Rafael for another season, so it depends on Rafael himself. My guess: we try to sign Hummels and if Rafael wants out Clyne makes sene. However, with Klopp possibly going to City, it might be difficult to obtain Hummels.
As for our attack, it will be very interesting what will happen regarding Memphis Depay. Smashley and Mata's current form and Adnan+ Di Maria makes that we're well stocked in the winger department. Does Memphis want to be a rotation player, or does he want to be a guaranteed starter at Spurs or Liverpool or whatever lower level club? Anyway, if we/Van Gaal wants him, we'll get him for sure so it's just a matter of wait and see. Players like Blackett, McNair and Wilson might be loaned out.
Having said all that, and obviously depending on how much City, Chelsea, but also very much Arsenal will strengthen their squad, I actually think we're quite good already. If it weren't for our poor start, we would've already challenged for the title this season with this squad. We can still improve as a team, results were great and we've peaked a bit, but imagine our midfielders scoring like in the last games, plus setting up Rooney properly once or twice, then we'd have scored even more goals. That's the next step.
